Re: [Discuss-gnuradio] gr-ieee-80211: UDP Warning and another error

[Johannes Demel]

Hi Sumit,

this is not an installation error. Your configuration is wrong. The 
argument `enb` must be of type bool but it is a string in your case.
I assume you use GRC to generate this flowgraph.
Open your USRP source block. Go to the `FE Corrections` tab and put in 
`False` in both fields. No `, ' or ". This will generate a line that says:
`self.uhd_usrp_source_0.set_auto_dc_offset(False, 0)`
instead of
`self.uhd_usrp_source_0.set_auto_dc_offset("False", 0)`.
This should fix your issue.

Cheers
Johannes
